History:

(Crime Cases Comics I#24/3) - In 1651, Marie married the Marquis de Bruyville but she had no affection for him, instead being in love with Captain Louis Crosse. Immediately after the wedding ceremony she met with Captain Crosse in the garden of the Marquis' home. Crosse admitted he'd become jealous by the wedding. Marie told Crosse one day she would be tired of the Marquis and then she would want his help in eliminating her husband. Just then, the Marquis entered the garden and Marie claimed Crosse had been forcing himself upon her. The Marquis had Crosse arrested and taken away.

One day Marie bribed her way into the prison to meet with Captain Crosse. Crosse had been placed in a cell with Exill, a famous poison developer and had memorized Exill's poison. Marie told Crosse that when he was free they would put the poison into effect. Crosse was released in 1653 and was eager to poison the Marquis but Marie observed they weren't absolutely sure the poison would kill quickly. To test the poison, Marie baked up poisoned cakes and served them to the patients of a charity hospital, posing as a benevolent woman. The following day she went by the hospital and saw many patients had died but it was being blamed upon a new disease from Asia.

Marie was left uncertain whether the poison had succeeded or not so she decided to test it again, this time putting it into her own father's medicine. After mere minutes, her father died. Marie went home to prepare more of the poison in her secret laboratory but she was interrupted by her husband's nephew, Jules. Hoping to distract Jules from what she had been doing, Marie suggested to Jules that he was in love with her. Jules admitted he was and she arranged to meet him in the library at 7:00.

Marie quickly told Captain Crosse about Jules. Rather than poison, Crosse resolved to murder him with his dagger. That night at 7:00, Marie met Jules in the library and served him wine. Crosse entered the library behind Jules armed with his dagger, but the light cast his shadow on the wall, alerting Jules in time for him to disarm Crosse.

Crosse fled from Jules into the home's secret laboratory, thinking Jules would be afraid of the dangerous chemicals in the laboratory. However, Jules simply stood at guard outside the laboratory. With no means of escape, Crosse was killed by the poison fumes in the laboratory. Once Crosse was dead, Jules summoned the police to his uncle's home and informed them the Marquise was responsible for the poison.

The Marquise attempted to flee in her coach but was apprehended within hours and arrested for murder. The Marquise was ultimately found guilty of poisoning 16 people. On December 4, 1653 she was executed by the guilotinne. The Marquis de Bruyville ultimately outlived her by many years.

Comments: Created by an unidentified writer and Jerry Grandenetti.

This story is probably based on the true-life case of Madame de Brinvilliers, an actual 17th century French noblewoman who conspired with her army captain lover to murder members of her family. I don't know why they changed the name - it's not like she was going to sue Marvel.
